COMBUSTION APPARATUS.

' Application filed November 13, B25. Serial No. 68,788.

The invention relates to improvements in air super-heating apparatus for use in connection with fuel burning devices of divers types such as furnaces, boilers, stoves and other heat producing units and has particular reference to an air super-heating means mounted in the feed door of such heat producing structures adapted to project the I a1r induction through various media for preheatingthe' cool drafts to direct and deflect same over the entire area of the combustion chamber'of the fire-box of such unit to produce live combustible gases for increasing the heat production of the fuel utilized and and to project such pre-heated air gases di- 'rectly into the combustion chamber of the heating unit in the form of highly charged gaseous molecules to increase the heat volume of the fuel, to thusly increase the distributive functioning of the heating-unit,

to decrease the quantity of fuel consumption and to greatly enhance the eiiiciency of the generating source.

Another and further object of the invention is in the providing of a preheating and gas forming structure constructed along pro-defined lines, 1n such form and deslgn as to increase the a1r reception and pre-heatmg chamber, having mounted therein an auxil iary super-heating means, and surface heating area in form of heat absorbing means, and a plurality of apertures so disposed with relation to the emitting end of the unit as to provide means for projecting the semigases andspre-heated air to be deflected in combustion chamber of the heater and within the prescribed zone thereinto assist and create proper combustion, in connection with any of the generally known typesand forms of heating structures.

In the following there is described the of the material savingv in the quantities of spray formation across the entire. area of the:

general embodiment of the invention the particular features being more particularly.

pointed hereinafter in the claims. 7

In the drawings Fig. 1 is a horizontal secsaid head; Fig. 3 is a longitudinal sectional view of the pre-heating combustion head illustrating the connective features of the air valve, the heat' absorbing surface thereto and the meansof primarily generating pregases and of the means of spraying the heated air directly to the combustion chamber of the heater; Fig. 4: is an end elevation of the spraying head showing the position therein of the air spray apertures and of the disposition thereon of the heat absorbing fins to increase the heating surface of said head; and Fig. 5 is a cross sectional viewof said head on the line 55 of Fig. 3 illustratin g the position therein of the baffle plate to separate the ingress of air to break same up during pre-heatingand the defiectionof same to the spray head of the burnrite projection.

Pipe connection or nipple 8 may be of any desired length and may be disposed to project within fire box 2 to a point of desired utility, and is externally threaded at 19 to receiye the threaded bore 20 of the air we heating combustion head 21. Said head 21 of a pre-determined shape and form tapering outwardly from the heel portion 32 to a point. to increase the internal heat capacity, thence tapering toward its front end i-eemi-eonically to 'toru'i anejector nozzle end re the central portion thereo'fbeing provided with a bore andplun' 26, the object whereof to provide means whereby one or more combustion heads may be hooked up in unit formation to increase the air pro-heating apparatue for larger sized and increased capacity heat generatingequipment.

Head 21 in cross section is square in form and at point 23 has cast therewith a battle plate 27. The caeing on all four snrjlacee thereof and extending from the heel 2:2 to the ejector and ill has jl orincd thertnrith a plurality of tins 2!) the object of which are to provide means ada 'rted to increaae the heat retaining and heat producing: s u'rface of the said combustion head til. By constructing; the head 21, with the [ins as d escrilnal the heating surface of the same is increased four times in excess of what an ordiimry smooth and nn-interrnpted surtace heating head would be provided with and there i provide a structure having: increased cttieiency as a comlniation unit.

Head 521 has formed internally thereof a primary heatingchamber 31,), and a eecondary heatingchamber 51 partitioned partly by battle plate 517, the open sides thereofprodmF ing passageways 32 For the. circulation and breaking; up of the pre-htaiti-d air, and said chamber has mounted therein a quantity of hand formed and packed steel or copper wire 33 to act as battling means and additional surfaceheating meane tor the air in its passage therethrougli.

It will be noted that substantially the entire combustion attachnlentis in form an air pre-hea tin 1- and superheating means an d that theairuin pass ng thei'etlu'oiig h from atmosphere. will reaching. the primary and see astra e; nch combustible before it cted through. the SERIES; of apertures Said apertures. are disposed.
